Answer:

33 Kwh

Step-by-step explanation:

let x = number of Kwh used

let y = total of bill

Therefore,  11.34 + 2.17x = y

Substitute y = 83 and solve for x:

⇒ 11.34 + 2.17x = 83

⇒ 2.17x = 83 - 11.34

⇒ 2.17x  = 71.66

⇒ x = 71.66 / 2.17

⇒ x = 33.023204147..

Therefore, Jordan can use no more than 33 Kwh to keep his bill to no more than $83
